A spinner with s equally sized slices has 2 red slices, 2 yellow slices, and 11
Afina-wow [57]

The experimental probability of landing on blue or red is 13/20.

The theoretical probability of landing on blue or red is 13/15.

As the number of spins increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal.

<h3>What are the probabilities?
</h3>

The experimental probability of landing on blue or red = (number of times the blue slice landed on by Amanda / total number of times the dial was spun) +  (number of times the red slice landed on by Amanda / total number of times the dial was spun)
= 11/20 + 2/20 = 13/20

The theoretical probability of landing on blue or red = (number of blue slices / total number of slices) + (number of red slices / total number of slices)

=  2/15 + 11/15 = 13/15
